When dealing with probability there is a range of values of the probability of an event. The probability of an event (E) is any number (fraction or decimal) between zero and one. (0≤ P(E)≤1)
When an event is certain to occur the probability of E is 1. This means that there is 100% that something will happen. This is why your sum of all the probabilities must add up to equal 1.
For example: Flip a coin. You have a 50% chance of it landing on heads and a 50% chance of it landing on tails since there are only two possibilities.
Let H=heads
Let T=tails
∑P= P(H)+P(T)=0.5+0.5=1
This is telling you, you have a 100% chance of it landing on either heads or tails.
If the event cannot happen the event contains no members in the sample space so its probability is zero.
For example: Roll a single die one time. Find the probability of rolling a 7:
This cannot happen so the probability is zero.

How big or small can a probability be?
Probability is measure on a scale of 1 to 0
What is the probability 10?
Probability = 10 is a very serious mistake since the probability of any event can never be greater than 1: so a probability of 10 is obviously a big error.
What happens if your rat breaks its leg?
there is a big probability that it will die.
What is the answer of probability of 2?
The answer is that you have made a very serious mistake since the probability of any event can never be greater than 1: so a probability of 2 is obviously a big error.
When the 25 skiers are sent down from the top of Big Bunny Slope they are sent one at a time. The probability that a random new skier in the group will fall at Big Bend is 0.3. What is the probability?
There is a limited length of question that can be asked. Your question is missing what probability it is you actually want. Please edit your question to include what you are wanting to know - if necessary abbreviate the details of the question to allow more length for the actual question, eg: 25 skiers are sent down a slope singly. the probability of each skier falling on the way is 0.3. What is the probability that...
What is the probability that one of the offspring mice will have black fur?
The answer depends on how big the litter is: as the litter size increases the probability of one black fur increases. But as it gets larger still, the probability falls because two or more black furs become more probable.
What does it mean to find the compliment of the probability of an event?
The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.
